Мікросхема STA339BW

STA339BW

The STA339BW is an integrated solution of digital audio processing, digital amplifier control, and FFX-power output stage, thereby creating a high-power single-chip FFX®solution comprising high-quality, high-efficiency, all digital amplification.

Features

•  Wide voltage supply range – 5 V to 26 V (operating range) – 30 V (absolute maximum rating)
•  3 power output configurations – 2 channels of ternary PWM (stereo mode) (2 x 20 W into 8  at 18 V) – 3 channels - left, right using binary and LFE using ternary PWM (2.1 mode) (2 x 9 W + 1 x 20 W into 2 x 4, 1 x 8  at 18 V) – 2 channels of ternary PWM (2 x 20 W) + stereo lineout ternary
•  2.1 channels of 24-bit FFX® 100 dB SNR and dynamic range
•  Selectable 32 to 192 kHz input sample rates
•  I 2C control with selectable device address
•  Digital gain/attenuation +48 dB to -80 dB with 0.5 dB/step resolution
•  Soft volume update with programmable ratio
•  Individual channel and master gain/attenuation
•  Two independent DRC configurable as a dual-band anti-clipper (B2DRC) or as independent limiters/compressors
•  EQ-DRC for DRC based on filtered signals
